Anti-Snap vs Anti-Bump vs Anti-Pick | Rank the Risk

Walk into any DIY shop and you'll see cylinders with four or five attack-resistance claims on the box. Anti-snap. Anti-bump. Anti-pick. Anti-drill. Anti-extract. It reads like a threat report. What the packaging won't tell you is that some of those threats are vanishingly rare in practice, and one of them accounts for the majority of cylinder-based break-ins across the UK. So let's rank them properly, using what the crime data and the standards actually say.

The Three Threats, Explained Briefly

Before the ranking, you need to know what each attack is. Not in vague terms. In terms of what a burglar actually does.

Snapping is the dominant method. A burglar grips the outside section of a euro cylinder with a mole wrench or a pair of pliers, applies brute rotational force, and the cylinder breaks at a pre-existing weakness point roughly level with the letterbox. The whole process, on a standard cylinder, takes under a minute. No skill required. The break point exists in almost every cheap euro cylinder because of how the cam is retained internally.

One detail worth acting on immediately: if your cylinder protrudes more than 3mm proud of the door furniture, it's significantly easier to grip and snap. A correctly specified cylinder, flush with or barely proud of the escutcheon, removes much of what the wrench needs to grab. It's often the cheapest part of the fix.

Bumping uses a specially cut bump key and a sharp impact to momentarily bounce the driver pins above the shear line, allowing the plug to turn. It requires the right key profile, a bit of practice, and a few seconds of noise at the door. It was a genuine concern in the mid-2000s when the technique spread through online forums. Today it's largely obsolete as a real-world burglary method, partly because most cylinders sold in volume now have basic bump resistance, and partly because snapping is quicker and needs no specialist key.

Picking means manipulating the pins into the open position using tension and a pick. It's skilled work. It takes time, a quiet location, and specific tools. Professional locksmiths do it. Burglars, as a general rule, do not. Police crime scene analysis consistently finds almost no evidence of picking in residential break-ins.

The Ranking by Actual Risk

Cylinder snapping is the primary cylinder attack in the UK. Industry research from the Master Locksmiths Association and the Secured by Design programme estimates it accounts for somewhere between 25 and 35 percent of door-entry burglaries where a cylinder was the point of attack. That figure circulates widely in trade materials and is consistent with what locksmith call-outs in Nottingham reflect. The Home Office publishes broader forced-entry data but doesn't break it down to that level of cylinder-specific detail, so I won't dress the estimate up as something it isn't. It's a reasonable, sector-sourced range, not a government statistic.

Bumping and picking combined account for a small fraction of that, and picking alone is so rare in residential burglary it barely registers.

The cylinder with eight anti-something badges that doesn't specifically address snapping is doing a lot of marketing for a small amount of protection.

What TS007 Actually Tests

TS007 is the UK's cylinder security standard, published by the Master Locksmiths Association. It's an MLA technical standard, not a full BSI standard in the way that BS EN 1303 is. Worth knowing if you're reading across spec sheets and wondering why you see both referenced. TS007 has three grades.

• 1-star: basic resistance. Many standard cylinders claim this without it meaning a great deal in practice.
• 2-star: meaningfully better. Tests include snap resistance at elevated torque and improved pick and bump resistance.
• 3-star: the grade that matters most for UK homes. Tests snap resistance across repeated attempts at high torque, plus drill, bump, and pick resistance. The specific torque figure in the standard is not something I'll quote from memory because the spec has been updated over time and I'd rather you read the current published version than rely on a number in a blog post.

A TS007 3-star cylinder has passed a snap test that standard cylinders fail immediately. That's why it's what I specify for any exposed exterior door, whether that's a terraced house in Sneinton, a buy-to-let in Lenton, or a ground-floor flat in Radford.

SS312 Diamond is a Sold Secure scheme aligned with the Secured by Design programme. It's not a police certification directly, but it's independently tested and the Secured by Design initiative is police-supported, so the association isn't unreasonable. In practical terms, SS312 Diamond and TS007 3-star demand comparable things from a cylinder. If you see either mark, the product has been genuinely tested.

Which Cylinders Actually Deliver

Brands I've fitted and trust at the 3-star or SS312 Diamond level: Ultion, Avocet ABS, and ERA Fortress. All come in standard sizes to fit most uPVC and composite door multi-point locks. Ultion in particular has a snap-shield that deliberately sacrifices the outer section rather than transmitting force to the cam, which is a neat mechanical solution to the snapping problem.

Mul-T-Lock produce high-security cylinders and have a solid reputation, but their UK certifications vary by product line. If a supplier quotes Mul-T-Lock as TS007 3-star rated, ask them to show you the current certificate for the specific model. That's not a slight on the brand; it's just good practice with any cylinder claim.

Expect to pay somewhere between £45 and £90 for the cylinder itself, depending on brand and size. Fitted price for a cylinder swap in Nottingham typically runs £80 to £140 all in. A standard cylinder that snaps in 45 seconds costs roughly the same to fit. The difference is the cylinder.

So Which Do You Actually Need?

Here's my direct answer.

Anti-snap protection is non-negotiable if you have a euro cylinder in any exterior door. It's the only one of the three that addresses a threat you're genuinely likely to face. Every euro cylinder on an external door across NG1 through NG11 should be TS007 3-star or SS312 Diamond rated. That's the minimum, and it should include checking the cylinder isn't sitting too proud of the furniture.

Anti-bump resistance is worth having because good cylinders include it at no extra cost. Don't buy a cylinder primarily because it says anti-bump, though. You're not meaningfully reducing your real-world risk by prioritising that over snap resistance.

Anti-pick matters for commercial premises, high-security applications, and situations where a targeted or insider attack is plausible. For a three-bed semi in Wollaton or a rental flat in Beeston, it's the last thing you need to lose sleep over.

The locks with the most claims on the box are not the most secure locks. They're often the most marketed ones. Look for the TS007 3-star kitemark or SS312 Diamond certification. Ignore the rest of the adjectives.
